ClinicalTrials.gov establishes one PRS account for an organization (such as a company, university, or medical center). Each PRS account is managed by one or more administrators who may add an unlimited number of user logins.

Please see How to Apply for an Account for information on who should apply for a PRS account and how to obtain a PRS account.
